HOIST FOR UNLOADING SHIPS.

SPECIFICATION forming part of Letters Patent No. 700,051, dated May 13, 1902. Application led September 12, 1901. Serial No. 75,142. (No model.)

To a/ZZ whom it may concern:

Beit known that LWILLIAME: I-IUTOHINes,

a citizen of the United States, residing atl Louisville,in the county of J e'erson and State of Kentucky, have invented a new anduseful Improvement in Hoists for Unloading Ships', of which the following is a specication. v

` My invention relates to a contrivance for unloading ships placed and contained entirely on the ship to be unloaded, as distinguished from various apparatus nowin general use for the same purpose which are placed and containedentirelyon-the dock to;

which the ship is to be unloaded.

My contrivance is devised solely for unloading coal, ore, and like bulky but separable material. l n

I attain the desired results by the mechanism illustrated in the accompanying drawings; in which- Figure l is a side elevation of the contrivance, together with a cross-section of the ship through one of its hatches and a part of the dock to which the ship is to be unloaded. Fig. 2 is a plan of a portion ofthe ships deck and a portion of the dock and shows the rela! tive position of the apparatusand the ships hatches. Fig. 3 is a cross section taken through the trolley-wagon and'trolley-track.

Similar letters refer to similar parts in all the figures.

A is a boom or trolley-track, of I-beam, channel, or built-up design, fastened to the deck of the ship D by means of the hinge F. in the pivoted shoe B. The boom or trolley-track A entends from the deck-shoe B lin an inclined direction upward across the ships hatch F and over the dock G and is held in position by the guy-lines Gr passing through sheaves attached to the masts H. Said masts are partly supported by Vthestays or rigging X X. By adjustment of the guy-lines Gr and by virtue of the hinge and pivot in the deck# shoe B the boom or trolley-track A may be raised orlowered vertically or swung laterally.

Upon the boom or trolley-track A a trolley-wagon J J travels,.rolling on its wheels K, and limited in its travels by the two stops L and L. At the stop Lv the wagon is represented by dotted lines. I prefer to make said boom or trolley-track a sin gle beam of I-beam section and to arrange the trolley-wagon so that vit runs on and astride of the bottom iiange thereof. From the trolley-wagon lJ .the bucket or shovel M of the automatic or self-loading and'self-dumping type is suspended in the following manner:

There are two lines N; butvthelower end Aof only one can be shown, theother being necessarily directly behind it on this elevation. One of these lines N is attached to the trolley-wagon J at O, passes around a pulley on the bucket M, thence up Yover a sheave P on the trolley-wagon, thence overa sheave at the outer end Q of the trolley-track, thence over a sheave -R near the `inner end of the booln, thence over a sheave S,'attached to the ships deck, over a sheave T,,attached to the deck, to the drum U of the hoisting-engine V. The other lineN is attached to the bucket M at O', thence runs through a series of sheavesv Vuntil they pass sheave,S,after which they separate, as shown on Fig. 2, this line passing through sheave T" and thence to drum U. This line may also, if desired, be attached to system of sheaves on the bucket.

In operation the bucket M is closed upon the material in the hold W of the ship by hauling on one of the lines N and is then hoisted by both lines N until in the position M it comes -in contact with vthe trolley-wagon J, when a continuation of the pull on both lines N causes the trolley-Wagon, with the bucket, to travel up the boom or trolley-track to the position J M", beingprevented from going farther by the stop L'. One line N is then slacked off, allowing the bucket to open and deliver its contents onto the dock C below. Both lines N are then slacked off, allowing the vtrolleywagon,with bucket, to return by gravity along the boom or trolley-track A toits original position J, being stoppedby stop'L. A further slackening of both lines N permits the bucket to descend again into the hold W of the ship, in readiness to repeat the above-described operations.

To further facilitate the operation of the trolley-wagon J on the boom or trolley-track "the trolley-wagon andv run thence through a IOO A, a third line may be attached to said trolley-wagon and lead over sheaves similar to R,

S, and T to a third drum on the hoisting-en-` gine. The object of this line is to assist gravity in bringing the trolley-Wagon back to its original position. The boom or trolley-track A is also arranged so as to be detached from its fastenings and lowered to the deck when so desired.

I do not claim as my invention the bucket M, the trolley-wagon J, the boom or trolleytrack A, or the hoisting-engine V, all of which are known by me to have been in use for some time in various modified forms and combinations for handling of material; but

What I d0 claim as my invention, and desire to secure by Letters Patent, is-

1. In hoists for unloading ships, the combination of a trolley-wagon J, an inclined trolley-trackA attached tothe deck of the ship by a hinge and pivot, and supported from above by guys; said trolley-track being a single beam of I-bearn section, with the wheels l of the trolley-Wagon running on and astride of the bottom flange thereof, together with lilies N attached t0 a bucket M, running through said trolley-wagon and along said trolley-track; said lines being controlled by engines, all for the purpose of lifting freight out of the ships hold toward the outward end of the trolley-track, in order to transfer it to a dock or'to another ship, substantially as described.

2. In hoists for unloading ships, the combination of a trolley-wagon J an inclined trolley-track A attached to the deck of a ship by a hinge and pivot, and supported from above by guys, together with lines N attached to a bucket M,runnin g through said trolley-Wagon and along said trolley-track; said lines to be controlled by engines, all for the purpose of lifting freight out of the ships hold toward the outward end of the trolley-track, in order to transfer it to adock or to another ship, substantially as described.
